Optimizes YouTube's theater mode for ultrawide monitors, expanding the video and chat layout to fill the tab. # YouTube Live Chat Wide Layout — English Store Description (v1.19) The perfect solution for watching YouTube live streams while multitasking in other tabs! "YouTube Live Chat Wide Layout" is a Chrome extension that enhances YouTube's theater mode (press 't'). It eliminates wasted space and black bars from the tab, filling the screen with just the video and live chat. With standard F11 fullscreen you lose access to other tabs — but this extension lets you **"keep the browser tab bar while expanding video and chat to their maximum size."** Great for background viewing on standard 16:9 monitors, and highly effective at eliminating black side bars on ultrawide displays. ✨ Key Features: **Eliminate Black Bars & Wasted Space** Even on ultrawide monitors, black side bars disappear and video + chat expand to fill the entire tab. **Freely Adjust Chat Width** Click the extension icon to open the popup and use the slider to set your preferred chat panel width. **Access to Action Buttons** Even in expanded view, the Like, Share, Clip, and other action buttons are automatically repositioned to the top of the chat panel — making it easy to support the streamer. Choose whether the bar sits at the bottom-left or bottom-right, and collapse it when it gets in the way. **Auto Live Sync** Automatically detects live stream delay. Small delays are corrected by gently increasing playback speed; large delays snap instantly to the live edge. Stay in sync with the chat and never miss a moment. The check interval (10s–10min) and lag tolerance (1–30s) can be freely adjusted with sliders in the popup. **Auto Error Reload** Detects playback errors and renderer/tab crashes (e.g. STATUS_BREAKPOINT) and reloads the tab automatically, up to 3 times per 5 minutes so a stalled stream recovers on its own while you are away. Toggle on/off via the popup. **Description Pane (Experimental)** Automatically displays the YouTube video description in a side pane during theater mode. Click timestamps to seek to that point; URL links are also functional. Toggle on/off via the popup. --- ## Version History v1.19 Fixed a mixed-language issue: parts of the popup (the Action Menu Position control, slider units, the delay readout, the collapse-button tooltip, the Description Pane "Loading…" text) always appeared in Japanese regardless of the browser language. These are now fully localized in all 8 languages. The popup UI was also refreshed — toggle rows are now full-width tap targets with the description shown directly under each label, switches and the segmented control were redesigned, values are shown as pill badges, and the layout now mirrors correctly for right-to-left languages such as Arabic. Also hardened the popup against an error when opened on a tab with no URL (e.g. chrome:// pages). v1.18 Added "Auto Error Reload": detects playback errors and renderer/tab crashes (e.g. STATUS_BREAKPOINT) and reloads the tab automatically, up to 3 times per 5 minutes. Added an "Action Menu Position" option (bottom-left / bottom-right) and a collapse button for the relocated Like / Share / Clip bar. v1.17 Improved Description Pane rendering: fixed an issue where 50 duplicate characters appeared between the video title and description body. YouTube's internal snippet elements are now skipped and the full description text is retrieved directly. v1.16 Experimentally added a Description Pane. Automatically displays the YouTube video description in a side pane during theater mode. Click timestamps to seek to that point; URL links are also functional. Toggle on/off via "Description Pane (Experimental)" in the popup. v1.12 Improved Auto Live Sync: now correctly detects DVR-mode live streams and no longer misfires on regular videos (fixed an issue where videos jumped to the end). Check interval extended to 30 seconds; snaps to the live edge only when delay exceeds 60 seconds; gently increases playback speed (1.1–1.15×) for delays of 8–60 seconds. Also fixed a thumbnail display bug on the YouTube home page and improved action menu restoration reliability. Added popup sliders to customize the check interval (10s–10min) and lag tolerance (1–30s). v1.07 Added "Auto Live Sync" feature that automatically detects and corrects live stream delay. Small delays are resolved by increasing playback speed; large delays snap to the live edge. v1.05 Added support for Turkish, Arabic, Traditional Chinese (Taiwan), Polish, and Russian. Fixed layout for RTL (right-to-left) languages such as Arabic: chat panel is now placed on the left, video on the right. v1.04 Added German language support. v1.03 The action menu (Like / Dislike / Share / Save / Clip, etc.) that was hidden below the video in expanded theater mode is now automatically relocated to the top of the chat panel. v1.02 Changed the support link in the popup to OFUSE. v1.01 Renamed the extension to "YouTube Live Chat Wide Layout". Added a slider to freely adjust the chat panel width (in pixels). v1.00 Initial release: Uses YouTube's theater mode (press 't') to remove wasted space and black bars, expanding video and live chat to fill the full width of the browser tab.
